Photodynamically induced virus inactivation appears promising in preventing transmission of enveloped virus infections in transfusible blood products. The potential for utilizing hypericin as a photosensitizer to inactivate key enveloped viruses in packed red cell concentrates (PRC) was evaluated.
Hypericin is a natural derivative of the common St. Johns wort plant, Hypericum perforatum. It has in vitro activity against several viruses, including bovine diarrhea virus, a pestivirus with structural similarities to hepatitis C virus (HCV). We conducted a phase I dose escalation study to
BACKGROUND
Recent interest in and evidence for the efficacy of St. John's wort (Hypericum perforatum) for the treatment of mild-to-moderate depression has led to speculation about its efficacy in other disorders. Hypericum's mechanism of action is postulated to be via inhibition of the synaptosomal
